Abstract: A magnetic separator having a chamber for receiving material to be separated. The magnetic separator utilizes magnets either along the outer surface of an elongated cylindrical chamber or as a fixed shaft of a helical conveyor. Two outputs are provided for discharging the non-magnetic material and the magnetic material separately from each other.

Abstract: The invention relates to process for recycling tires and other recyclable materials. The process includes a series of steps designed to reduce a rubber or polymer tire into pulverized material. The process involves first shredding the tires or recyclable material into chips. The chips are then cooled to cryogenic temperatures at which said pieces become brittle. The brittle pieces are then pulverized in the second step. Pulverized material is then screened, removing large chunks of rubber or polymer from the mixture. Finally, the remaining fiber and magnetic material is separated out of the pulverized material, through the use of a magnetic separator and a vibrational (fiber) separator.

Abstract: There is provided a cooling device for lowering the temperature of rubber or polystyrene materials for recycling purposes. The cooling device has an input feeder which inputs the material to be treated into a cooling chamber. The cooling chamber is an elongated chamber. The cooling chamber receives cold air from an external air refrigeration unit and circulates that air within the chamber. The material input into the cooling chamber is circulated therein by a circulating shaft. After 15-20 minutes, the input material is discharged through an output on the opposite end of the cooling chamber. The temperature of the material discharged is -80.degree. C. or lower.
